Actuators

Logic of naming actuators in VW-group is simple it contains "N" + actuator number. The actuator number is unique. Here you can find fitting location, connectors and some basic information about actuators.

To our mind, actuators information is reference, so there is only simple search by number.

I The test is only to be performed in the event of lack of power above specific engine speed ranges

   or if a fault is stored.

I The changeover of the intake manifold from the long to the short intake travel occurs

   dependent on engine speed.

 

Intake manifold changeover:

Measured value block 095: (displayed in the test procedure)

1) Engine speed [ rpm]

2) Load  [%]

3) Coolant temperature [°C]

            80 -  105

4) Intake manifold changeover

       IMC-V OFF / IMC-V ON

           

Increase the engine speed to approx. 5400 rpm to initiate the intake manifold changeover.

 

Intake air changeover:

Measured value block 097: (displayed in the test procedure)

1) Engine speed [ rpm]

2) Load  [%]

3) Coolant temperature [°C]

            80 -  105

4) Intake manifold changeover

         ON / OFF
